Researchers writing in the journal Injury Prevention say that even just a little bit of alcohol could be causing fatal car crashes. The researchers focused on “buzzed driving” rather than drunk driving, which is considered as having a BAC of 0.01 percent to 0.07 percent versus 0.08 percent and above.

Self-driving vehicles offer the promise of significant benefits to society, but raise several policy challenges, including the need to update insurance liability regulations and privacy concerns such as who will control the data generated by this technology.

According to a new study by IHS, the world's roadways will begin seeing driverless cars by 2020, with 54 million self-driving vehicles on the road by 2035, worldwide. The study also predicts that almost every personal, as well as commercial, vehicle in use after 2050 will be self-driving.
